PROFICIENCY TESTING TO CHECK ERRORS IN FOOD LABORATORY TESTING:2AbstractThe report provides a quantitative description in the area of proficiency testing to check errors in foodlaboratory testing in the context of Eurofins Laboratory, Penrose Auckland. It starts with a briefdescription of the Eurofins company and its position in the industry before exposing the problem oferrors. The recent past has recorded a number of misunderstandings between the clients, the public andthe company in its role of providing analytical services. The analytical methodology of proficiency testingis described in relation to accreditation, companies are required to establish a pre-requisite ofcompliance to the set standards and are therefore allowed to operate before full accreditation. The fieldprocess is described so as to identify the errors that alter the truth of laboratory food testing results. Theindustry requirements are then established as the guiding standards.IntroductionEurofins Laboratories has operated in the field of bio-analytical testing for a considerable period. Theorganization is missioned in contributing to the health and safety to the global population throughprovision of high quality laboratory testing and advisory services. The operations of the firm benefits theinternal stakeholders, in this place the employees and the shareholders at the external point of view.The focus of the company is the satisfaction of the customers through listening to them and providinghealth and safety guarantees which exceed their expectations. A series of innovative are sought to addvalue to the customers to help them attain their objectives[ CITATION Pau161 \l 1033 ].The area of proficiency testing in Eurofins assures timely and accurate results by applying technology inthe testing processes. Proficiency testing is always conducted appropriately by qualified staff to checklaboratory errors in food testing. The integrity of staff cannot be compromised because of the drive torespect the customers and revealing an ethical conduct in all the operations of financing and business atlarge[ CITATION Yan16 \l 1033 ].The analytical processes in testing of food products have beenbroken down to characterize for safety, purity, authenticity, identity, origin and composition so thatthere is appropriateness in the error-checked results.Research objectives, questions, hypothesis and aims1.ObjectivesThe objective of this report is to reveal the effectiveness of proficiency testing to check errors in foodlaboratory testing citing the vital role of safeguarding the health of consumers of food products. Errors

Theproblem of errors in the industry guided by strict standards is found to be difficult to beeliminated[ CITATION Ana12 \l 1033 ].Literature reviewResults reliabilityA number of researches have been done concerning food laboratory testing with emphasis in accuracyof results.This implies that the efficacy and the reliability of the test results are central in the research.This is fundamentally because the more accurate the laboratory testing results are, the higher thelikelihood of the researchers making informed conclusions and decisions. The opposite is evidently true.Relevant systemsProficiency testing has been described to comprise a system within a laboratory to conduct regulartesting and comparison of results.As such, the presence of the relevant systems in the laboratory isindispensable. This is to remarkably facilitate routine testing and consequently expedite the analogy of

This will promote the identification of similarities and disparities in the testresults.Score production and proficiency testing efficacyPortions of identical food materials will be tested in various stations and then analyzed independentlybefore compiling the findings to produce a score that relates to the accuracy of results.This is necessaryto enable the preparation of a final score that is holistically reflective of the entire specific foodmaterials tested.The available research identify proficiency testing as the most effective way used bylaboratories to perform checks on errors[ CITATION Van14 \l 1033 ].A robust scheme of proficiencytesting will give laboratory directors confidence in equipment, staff, methodologies and also anassurance to the deliverance of results at the qualities required by customers[ CITATION Iva17 \l1033 ].The critiqueHowever, the area of complex data has been overlooked by researchers.This implies that researchersoften ignore the relevant significance of the convoluted data. This can be detrimental if not diligentlyresolved.When test data becomes sophisticated, high costs are incurred by the laboratory on staff andequipment.That is, more financial resources are expended in paying the laboratory employees as wellas in the procurement, servicing and maintenance of the laboratory equipment. As a result, the cost ofoperating the business upsurges.Similarly, the prices of the end products from the enterprises increase.The available systems in theindustry are ineffective and this makes it difficult to identify the particular test problems.This is partlyattributed to the fact that a majority of the businesses are reluctant or rather are not fully committed toinvesting in fully functional systems. As such, the few available systems end up being overstretched yetthey are ineffective. Sadly, this hinders the identification of the relevant particular test problems.The z-scoreThe z-score is the tool that analysts use to compile test results in the laboratories[ CITATION Tim16 \l 1033 ].The score tests distribution of test data across the normal distribution and a null hypothesis.The theory is based on a central limit to test for normal distribution of large samples. The z-score haspredetermined significance levels with single critical values each which allows for many tests to be done.Proficiency tests will be deemed as appropriate if the samples to be tested are distributed to various
